Abstract : The U.S. Army Defense Ammunition Center (DAC), Validation Engineering Division (SIOAC-DEV), was tasked by the Defense Ammunition Logisitcs Activity (AMMOLOG) to monitor environmental conditions of ammunition items in open storage under tarpaulins at Ft. Bragg, NC. Results from monitoring indicated that the tarpaulins provided little to no protection from the effects of solar radiation with portions of the ammunition reaching temperatures of 140 degrees Fahrenheit. The tarpaulins did, however, provide sufficient protection from moisture with the humidity under the tarpaulins remaining at or below the ambient humidity.
